/* FIX-M1: mobile no longer uses position:fixed for the palette (WordPress
   themes commonly apply a transform to <body> for their own mobile-menu
   animation, which silently breaks position:fixed everywhere below it — the
   panel then drifts with the page instead of staying pinned to the screen).
   Instead .dqp-pal-inline sits in normal document flow right after the
   question area, with the grid/legend/action-buttons collapsed by default
   behind a "Palette ▾" toggle so it doesn't eat permanent screen space. */
